About gas safety certificate (cp12) in Chatham

Chatham is a medium town of around 80,000 in Kent. The housing is mostly period cottages, Edwardian villas and 1930s semi-detached housing alongside newer commuter developments. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like ME4, ME5 tend to be quicker jobs with standardised fittings. Local trade prices sit in the same ballpark as the UK average, with Kent firms quoting close to national rates.

A lot of South East firms work both London and local jobs. Rates usually track London with a small discount, so you're rarely getting a bargain. Peak season runs May to September and good tradespeople can be three to four weeks out. Out of season is the time to price round.

Heating is a regulated trade. Gas Safe for anything gas, OFTEC for oil, HETAS for wood burners and stoves, MCS for heat pumps. The bulk of the price is the engineer's time, roughly £300 to £500 a day in 2025, plus the appliance. A summer quote on the same job is usually 10 to 15 percent less than a winter emergency one, so don't leave an ageing boiler until October.
